Over 300 Children Infected in Major Measles Outbreak at North London School.

Over 300 suspected measles cases have been reported in a north London school outbreak since January 2026, with 59 confirmed cases in Enfield alone, making it the hardest-hit area in England. The outbreak, primarily affecting unvaccinated children under 10, has led to hospitalizations and prompted health officials to urge MMR vaccination, as the UK has lost its measles elimination status due to low vaccination rates. Officials warn the actual number may be higher and are expanding access to clinics to boost immunization.
